On my weekly test environment, cgroup related cases and runpwtest01 case
works well. And other cases reports TCONF because of kernel config ie
runpwtests_exclusive0[1-6].sh.

Agree, so I have tried them and it works well, so I don't think it will
hide because it only removes old kernel version check.
